FROM THIS EPISODE

The gap between the rich and the poor is growing so fast both Republicans and Democrats see a long-term threat to the economy. Are the policies of Big Government part of the problem? Is the Obama Administration making things worse? Also, North Korea threatens strikes as the UN imposes new sanctions, and researchers put a price tag on gun violence.

The UN Security Council has unanimously approved new sanctions on North Korea, despite its threat of nuclear retaliation against the United States. Even China, North Korea's principal ally, helped the US draft the resolution. Colum Lynch covers the UN for the Washington Post.

Today's Dow Jones Industrial Average jumped over yesterday's record high. It's a "golden age" for corporate profits, which are the largest share of the economy since 1950. But the portion that goes to employees is close to the lowest since 1966. Both liberal and conservative economists are worried because the gap between the rich and the poor is growing so fast. The gap is also alarming Democrats — and some Republicans. Eighty-five billion dollars in federal sequestration could increase unemployment by 700,000 jobs without making a dent in the markets or corporate earnings. How much is the Obama Administration to blame? Is there a potential fix that might appeal to partisans on both sides?

A new report puts a price tag on gun violence: $12 billion a year, including $1.4 billion to US taxpayers -- for Medicare and Medicaid payments to treat victims in emergency rooms. The Senate Judiciary Committee today began debate on gun safety proposals in the wake of the Sandy Hook massacre. Chairman Patrick Leahy, Democrat of Vermont, held up a piece from yesterday's USA Today on how gunshot wounds are driving up the cost of health care. We hear from Kelly Kennedy, who wrote the story, and from RAND analyst and former emergency room physician Art Kellermann.
